The valve `69 is normally heldin the positionillustrated in Fig. 1 to direct huid under pressure through the conduit61 and into the forward end rof the cylinder 59. W'hen the solenoid 16is energized, the valve 69 is actuated to direct iluid under pressurethrough the conduit 68 into the'rear end of the cylinder 59 to move thepiston 58 towardlthe frontend of the cylinder. i Y

lA'deflector roll 8| is journaled at its ends in the frame 6 and :isprovided withv a corrugated surface for engagement with thefrontedge ofthe advancing sheet 1. As illustrate-d in Fig. 1, the deector roll isrotated ina clockwise direction to direct the ysheet material upwardlybetween the upper conveyor- II and intermediate conveyor 28. Thedeflector roll 8| is rotated in a counterclockwise direction to directthe sheet material :between the intermediate :conveyor 28 and the lolwerconveyor I2. Theameans employed'for driving ,and control ling theoperation ofthe winding apparatus is diagrammatically.'illustrated inFig. 2 in the drawings. The flying shear members and 9 `are driven-intimed relation byl means of a pair ofy meshing gears 82 and 83,v theshear member '.8 being vdriven by means of a suitable electric motor 84,acting through a suitable transmission 86; A pair of gears .81 and 88are' secured to the conveyor'driving shafts I4 and 22, respectively, andare driven by means of an electric motor 89 actingthrough suitable geartransmission 9|. A gear 92 is `secured/to the .intermediate -conveyordriving'shaft 323 and is vdriven-by a reversiblel velectric motor 93`acting'through suitable transmission 94. A brake drum 96 is interposedin the power transmission shaft between the motor 93"and the/drivingshaft 33 to be engagedby a friction lever 91 which is-movedintorfrictional engagement with Vthe brake drum 96by means ofv acompression spring 98. The brakeqarm 91 is drawn :out of frictionalengagement withthe brake drum 96 by means of a plunger 99 actuated by -asolenoid The mandrel-29 is [driven by a motor |02 acting through asuitable transmission ID3; and the mandrel 3| lisdriven by a motor |04through a suitable transmission |06. The motor 84 is connected to asource. of` current by means ofleads |01 and |08, Aandaswitch i lead|212.

mandrel 3 I.

09 is interposed in lea-d |08 to control the operation of the motor. Themotor |02 is connected to a source of current through lead I|I, switchI|2 and lead H3; while the motor |04 is connected to a source of currentthrough lead Ill-I, switch I I2 and conduit ||4. The reversing motor 93is connected to a source of current through the lead IIB, 'rotary switch|I1 and lead H8. The solenoid 16 is connected to a source of currentthrough lead II9, rotary switch |2I, and The solenoid |0I is connectedto a source of current through lead II 6, rotary switch 'I`I1 and lead|23.

`-In the operation of the Winder apparatus, the sheet'material 1 isadapted to be moved continuously-through the feed rolls `4-|| and thenbetween the forward ends of the upper and lower conveyors II and |=2.When all the con@ veyors are in the positions illustrated in full linesin Fig. 1, the forward edge of the advancing sheet 1 is engaged by thedeector roll 8| which is turning in a'clockwise direction to direct thesheet material upwardly between the upper conveyor II and intermediateconveyorV 28,. The forward edge of the advancing sheet is engaged in oneof the'recesses provided in the collapsible mandrel 29 which is rotatedin a counterclockwise direction by the motor I 02 until a roll ofsufficient diameter is formed thereon. ,1

lWhen the roll of sheet material on the mandrel 29 reaches apredetermined diameter, the switch |09 is closed to cause the flyingshear to rotate one complete revolution to cut the sheet 1 trans-Versely. During rotation of the ilying shear, the rotary switch I|1Vacts to break and then complete thev -circuit to reverse thedirectionof rotation of the motor 93 and thus acts to reverse "thedirection of rotation of the drivin-g pulley 36 `of the intermediateconveyor 28. The deector roll 8| is then caused to rotate in acounterclockwise direction by means of a train of gears comprising adriving gear: |26, an intermediate gear |21 and a driven gear `|28.During alternate `revolutions of the ying shear, the solenoid `16 l isenergized 'to actuate lthe four-way valve 69 and Vcause vthe piston 58`to -move outwardly to pivot the rocker arm 52 which, in turn, actsthrough connecting rods 43 vand 41 to raise the conveyors l|| and l2 andlower the conveyor. 28 to the position indicated indotted outline. The

switch ||,2'is moved to its dotted'position to complete the circuit tothe motor |04 to rotate the It will thus be seen that the forward edgeof the advancing sheet 1 will first be engaged and directed by thedeilector roll 8| into position between a pair of endless conveyorswhich in turn act to direct the advancing sheet toward a mandrel forwinding. The mandrels 29^and 3| are preferably of the collapsible typeto facilitate removal of a roll oi sheet material from one mandrel whilethe sheet material is being wound on the other mandrel. During operationof the'i'lying sheanit will be noted th'at the rotary switch II1 breaksthe circuit to the solenoid 16vand permits the friction arm 91 vto bemoved into frictional engagement with the. brake drum, 96 by means ofythe compression spring 98 to stop rotation ofthe -motor 93 and theparts driven thereby prior to reversal of rotation of the motor. Duringthe operation of the apparatus, theupper and lower conveyors Y| and I2are driven continuouslyY in the directions indicated by the arrows bymeans ofthe motor 89. 1 It is. contemplated 5. that the switches: H19:and VH2 maybesoperated manually ar-automatically. l-
